OTRC: Zach Galifianakis says 'Hangover Part II' character is a dumb mouth-breather

Zach Galifianakis' character in "The Hangover" managed to be naively catastrophic after accidently drugging his "Wolf Pack" groomsmen. In "The Hangover Part II," he is back to potentially ruin yet another wedding but the actor says his role is particularly easy for him.

"My character's just so one-dimensional, it's so easy," Galifianakis said in an interview provided by Warner Bros. Pictures. "He's just a dumb guy who mouth-breathes and says really bizarre things, so that was pretty easy to do."

In the movie, which was released during Memorial Day weekend, the four stars (Bradley Cooper, Zach Galifianakis, Ed Helms and Justin Bartha) travel to Thailand for Stu's wedding. Helms plays the character who famously lost a tooth in the first film and ends up with the now infamous Maori-inspired face tattoo the eve of his wedding in the sequel.

In the first R-rated comedy movie, which hit theaters in 2009, hijinks ensued when the four arrived in Las Vegas for a bachelor party ahead of the wedding of Doug, played by Bartha.

"I think this one, the sequel has upped the ante as far as action and the extremes of how far Todd likes to push things," Galifianakis said. "We were shooting a scene for the second one and you hear Todd yell, 'cut, wow that might have been too much for me to even put in a movie.'"

Galifianakis admits that he didn't want to return home after filming in Thailand because it was so "un-boring" there.

"I don't really want to go back because I think I might be bored when I go back to the United States. This might be the most un-boring place. I just love it. And then as far as the islands and where we shot in Krabi, it's a different pace but the people are just the best here, they really are just the best."

The comedian is best known for his "Hangover" character and roles in movies like "Dinner for Schmucks" and "Due Date." He also does regular comedy videos on FunnyOrDie.com called "Between Two Ferns," where he interviews celebrities between two potted plants. The funny man admits that he has a similar sense of humor to "Hangover" writer/director Todd Phillips.

"Todd's sense of humor and, I can speak for myself, Todd's sense of humor are similar in certain ways. It's all about trying to surprise an audience and not to telegraph a joke necessarily and when a joke hits you and you don't really expect it, I think that's... Todd and I really like the unexpected... I think the difference between a good comedy director and one that's not so good is that Todd also lets the actors have freedom to try things out and sometimes he likes it and sometimes he doesn't."

While it was rumored that a lawsuit over the tattoo artist's copyright on the Tyson tattoo would possible hold back the film's release, it was announced this week that the film would still open in theaters on May 26.

Galifianakis, meanwhile admits that he never imagined he would be friends with the retired boxer.

"He shows up for a couple of days and it's just fun to see him," Galifianakis said of Tyson. "I never thought that I would be buddy-buddy with Mike Tyson and I'm sure he thought the same thing about me."
